BO - stinky!
Color: White, Size: Medium
Shirt itself fits great and has a soft almost velour feel to it. Ribbing nice and not itchy. However, it arrived with the most disgusting baked-in body odor smell, as if someone had sweated heavily in it. Unsure if it’ll be able to be laundered out.

Buy it
If you're looking for a comfortable thick and nice turtle neck this is the one. It's nice and form fitting nice weight to it to keep you warm. But not to thick that you cant just wear it on a regular sunny day if you wanted. The design pattern Is also very nice. Can dress it up or down. I bought the black and then immediately bought the rust orange color for my friend once he tried on mine he wanted one immediately so I gifted him one. He loves it. Definitely worth the buy. Excellent quality. I bought a Large 5"11 165lbs
